▎ 摘  要

NOVELTY - Manufacturing antibacterial regeneration filter comprises (1) preparing filament for 3D printing by cutting and extruding waste polymer, (2) 3D printing the filament to produce an output in the form of a fabric, (3) applying an adhesive to the surface of the output, and (4) coating antimicrobial particles on the output to which the adhesive is applied. The extrusion of step (1) is performed by dividing the zones set at different temperatures, the temperature of the first zone is 60-90° C, the temperature of the second zone is 200-280° C. The 3D printing in step (2) is performed at a nozzle temperature of 230-290° C, a bed temperature of 100-140° C, printing speed of 80-120 mm/second, at height of 0.1-0.2 mm/layer, the output has a surface structure or a lattice structure in the form of a fabric in which wefts and warps are woven. USE - The method is useful for manufacturing antibacterial regeneration filter. ADVANTAGE - The method is simple and suitable for manufacturing any shape. The filter has good harmful gas adsorption properties and antibacterial properties. DETAILED DESCRIPTION - Manufacturing antibacterial regeneration filter comprises (1) preparing filament for 3D printing by cutting and extruding waste polymer, (2) 3D printing the filament to produce an output in the form of a fabric, (3) applying an adhesive to the surface of the output, and (4) coating antimicrobial particles on the output to which the adhesive is applied. The extrusion of step (1) is performed by dividing the zones set at different temperatures, the temperature of the first zone is 60-90° C, the temperature of the second zone is 200-280° C.
